Western NSW continues to struggle with a dry season, and now Livestock Health and Pest Authorities are warning stock owners they face fines if they don't follow the rules when it comes to travelling stock routes.

As pasture becomes harder and harder to find, some stock owners are looking to find alternative grazing on travelling stock routes. But there are strict rules that need to be followed.

Colin Betts, senior ranger for the Darling LHPA says it's not complicated to get the paperwork in order to put your stock in the 'long paddock' but says the western travelling stock routes are already looking pretty sketchy when it comes to relief pasture.

"The routes in the Darling LHPA are very short of feed now and we're very short of water as well.

"If people are looking to put stock on the road, they probably want to go further east."
